Chemical Structure
Description
Mycophenolate Mofetil EP Impurity B Oxalate (C29H42N2O9C2H2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Mycophenolate Mofetil EP Impurity B Oxalate (CAS CATO-C4X-151529) is a certified pharmaceutical impurity reference standard with the molecular formula C29H42N2O9C2H2O4 and a molecular weight of 652.69 g/mol.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Mycophenolate Mofetil EP Impurity B Oxalate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
